vdev ioapic

Synopsis:

vdev ioapic options

Options:

hostvector vector

Associate the first guest interrupt of the I/O APIC with the host interrupt number specified by vector; associate the second guest interrupt with vector +1, etc.

If a guest interrupt is marked as a pass-through target and no host vector is explicitly provided, this association provides the host interrupt vector number to use for the guest interrupt.

intr apic

Downstream interrupt to raise.

loc addr

Base address of the device registers.

name name

Name to use for upstream interrupts referencing this PIC.

For a list of options available to all vdevs, see Common vdev options at the beginning of this chapter.

Description:

x86 only. The ioapic vdev emulates an Intel I/O APIC programmable interrupt controller (PIC).
